Abstract
A theoretical treatment of the dielectric effects on the polarizability of an circular aperture in a perfectly conducting plane has been perfomed. A solution is developed for computing the electric polarizability of an aperture in a ground plane with infinite small thickness surrounded by a dielectric half space on side and a dielectric layer of finite thickness on the other side. An appropriate boundary-value problem is formulated and reduced to a set of dual integral equations. Later, we will formulate a Fredholm integral equation of the second kind with compact kernel and from the solution of this integral equation the electric polarizability of the aperture is calculated. The results of the calculations are reported in the form of graphs for the variations of the electric polarizability with the dielectric constant of the dielectric half space as well as the dielectric constant and thickness of the dielectric layer.
